Problems solved by technology

The brake using the contact force has the shortcomings of wearing due to friction, noise, high temperature and the resistance effect is unstable.
When the rotor is rotated, the rotor cuts the magnetic field and thereby produces an induced eddy current, causing an eddy current break effect to the rotor.
The drawback is that it needs a man-made effort to adjust the distance of the magnet to control the magn

Embodiment Construction

[0018]Referring to FIG. 1, the present invention provides a self-sourcing exercise bike with a linear digital control magnetic resistance braking apparatus. The exercise bike comprises a generator 10, a power converter 20, a digital control system 30, a magnetic braking resistance 40 and a LED control panel 50.

[0019]The generator 10 is a permanent magnetic three phases induction generator. It transfers the mechanical energy from the user or rehabilitant pedaling the bearing to rotate the induction armature of the permanent magnetic three phases induction generator to generate electric power. It provides the power for the digital control system 30, the magnetic braking resistance 40 and the LED control panel 50 through the power converter 20. The rotating bearing is a permanent magnet and fastens by a flywheel in the outer ring.

[0020]The power converter 20 is a switching power converter for converting the electric energy of the permanent magnetic three phases induction generator 10 t...

Abstract

A self-sourcing exercise bike with a linear digital control magnetic resistance braking apparatus comprises a generator, a power converter, a digital control system, a magnetic braking resistance and a LED control panel. This apparatus uses a linear control method to control the change of the magnetic resistance, and the magnetic resistance braking apparatus uses a method of changing inductance and a controlling way thereof to achieve the goal of controlling the variation of the magnetic resistance braking force. This bike makes the user or rehabilitant to linearly adjust the resistance force or torque according to the speed of the exercise bike and the presetting resistance force, and easily start up the power system in the initial stage.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a self-sourcing exercise bike with a linear digital control magnetic resistance braking apparatus. In particular, this invention provides a linear control method to control the change of the magnetic resistance, and the magnetic resistance braking apparatus uses a method of changing inductance and a controlling way thereof to achieve the goal of controlling the variation of the magnetic resistance braking force.[0003]2. Description of the Related Art[0004]The exercise bike is a very popular product for exercise or rehabilitation in the house, gymnasium, and hospital. The resistance or brake apparatus in a self-sourcing exercise bike could be divided into friction brake, oil-pressure brake, electric-magnetic brake and eddy-current brake. To sort them by force, the friction brake and oil-pressure brake are belong to contact force, the electric-magnetic brake and eddy-current brake are belo...
